Investigating storage provider registration problems
Once you have VSAN configured and enabled, you may find that you are unable to create storage policies because VSAN storage providers are not registered. This process should happen automatically but, if the providers become unregistered, then we will need to force the system to refresh the provider registrations before VSAN policies can be created, modified, or applied.
It is likely that there is a provider registration problem if the VSAN-related policy options are not present when you go to create a storage policy or if no policy information is reported for VMs/virtual disks.
Getting ready
You should be logged into vSphere Web Client as an administrator.
How to do it…
To validate that the storage providers have become unregistered, in vSphere Web Client navigate to Home | Hosts and Clusters | vCenter | Manage | Storage Providers.
If there are no providers registered, ensure that TCP port 8080 is open between vCenter Server and the ESXi hosts...
